I texted a random girl on Facebook.

Me: You're kinda adorable. Have you ever gone out with a guy more attractive than yourself? I shall be your first.

Her: Don't get fooled by my pics. I'm not as adorable as you think.

Me: Hey, it's okay. Don't sell yourself short

Her: Sorry, I'm not interested. Thank you.

I didn't reply after that, after all there's no point in replying. I would like to know where did I screw it up. Any pointers are appreciated.
